Philly Cheese Steak Sandwich

We slice the beef into very thin strips; slightly freezing the meat beforehand makes slicing easier.

We heat oil in a frying pan over medium-high heat.

We add the beef slices to the hot pan.

We season the beef with salt, pepper, and steak seasoning.

We sauté the beef until fully cooked and browned, then remove it from the pan and set it aside.

In the same pan, we add the onion slices and sauté until they soften slightly.

We add the sliced mushrooms to the onions.

We season the onion and mushrooms with salt and black pepper.

We cook them until they wilt and turn golden.

We add butter and brown sugar to the mixture to enhance caramelization and flavor.

We return the cooked beef to the pan and stir to combine with the onions and mushrooms.

We place the cheese slices on top and cover the pan until the cheese melts completely.

We gently mix everything together until the melted cheese is evenly distributed.

We stuff the sandwich bread with the beef and cheese mixture and serve it hot.
